 Depending on the circumstances, I think a better option might be to change 
intr to something the users aren't likely to hit accidentally.  That way, 
you still have an "interrupt" key available if a user actually needs it.  
The key can be the same for all users, but if you have different terminal 
types, that could be an issue (not all keyboards have the same keys).

 For example, we wanted to use Delete as a "hot key" in our application 
(along with Insert, Home, End, etc.), so we changed intr to something else.

 FWIW, we used "stty intr \^\~".  On most US terminal keyboards, that was a 
Control-tilde (Control and the character to the left of the number 1 above 
the letters, either "`" or "~").  On an SCO console it was Control-6 (the 6 
above the letters, not on the numeric keypad).

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
